Title: Treatment of nitrogen fluoride
Inventor: KATAMURA KOICHI
IPC: B01D53/34
Filed: 1985-06-11
Abstract: PURPOSE:To remove nitrogen fluoride efficiently and safely by bringing nitrogen fluoride contg. NF3 and a decomposition material thereof into contact with metallic Ti, allowing these to react with each other and recovering F2 as TiF4. CONSTITUTION:Nitrogen fluoride contg. NF3 and a decomposition material thereof is brought into contact with metallic Ti preferably at 250-400 deg.C temp. and allowed to react with each other. Since TiF4 is formed on the surface of Ti and immediately gasified and always the fresh surface of Ti is exposed, Ti can be effectively utilized. Gaseous TiF4 is cooled and easily recovered as solid TiF4 from the exhaust gas and can be removed and also can be removed by the washing with water and an alkali aq. soln. or the like.

IPC: G03B7/099
Filed: 1994-06-07
Abstract: PURPOSE:To decrease the influence of parallax exerted on a camera where a finder optical system and an autofocusing optical system are arranged in a line. CONSTITUTION:Objective lenses 61 and 62 constituting the autofocusing optical system are arranged in a lateral direction at the right side position of a photographing lens 2 forming the optical axis of the finder optical system F.

SOLUTION: The main body of the automatic ticket examination machine is installed at a station that is located between stations B and C, and the passenger ticket which is put into the examination machine is a make-connection adjustment ticket that is issued by a make-connection adjustment machine installed at the station B and is available up to a station D based on a commutation ticket available between the stations A and C. Under such conditions, the data recorded on the make-connection adjustment ticket put into the make-connection adjustment machine are read to extract the station B where the make-connection adjustment ticket is issued and the station C where the relevant passenger get on a train by the adjustment ticket.  As the station of the ticket examination machine exists between the station B that issued the make- connection adjustment ticket and the station C where the passenger gets on the train, the wrong use of the adjustment ticket is decided. Thus, the ticket examination door is closed to reject the leaving of the passenger.

Filed: 1995-05-25
Abstract: PURPOSE: To prevent the vehicle at an adjacent driving lane from being detected by mistake even in a curved road by limiting the correction angle in the direction of the irradiation of beams with an upper limit. CONSTITUTION: A sensor part 11 applies light to a specific region in front of a vehicle and receives a reflection wave from an object in the region and sends it to a radar ECU 13.

The distance DR is set to the upper-limit parameter for the distance D. In the case of a distance D<=DR, a forward vehicle is tracked as before and sight is set to the distance DR in the case of a distance D>DR, thus calculating a beam correction angle θa=sin<-1> (Dr /2R) of the sensor part 11.  The value is instructed to a steering part 12 to correct beam application angle, thus properly detecting an obstacle according to the condition of a curve.
